Yeah, re the birdies, I was going to say the same thing, but forgot.
Re VHF mil freqs, I live under a military training route

and there are a couple MOA training areas nearby, so it's pretty active here.
Re ACARS, I've tried that, and got a few hits, but that's not real active here. Didn't have much luck for some reason.
Re 8992, I'll have to try that. Have several HF radios, although I recently took down my HF antennas (basically a trade with xyl for more sat dishes). I can't remember the freq, but I used to listen to HF from some island in the Atlantic, which was particularly active and interesting back during the first gulf war.

sorry this drifted off topic quite a bit.
